Title: Plasma x-ray generating device
Inventor: KATO YASUO
IPC: H01J35/22
Filed: 1986-12-05
Abstract: PURPOSE:To enable an impure gas blown off from an electrode to an operating gas to be decreased, a variation of a X-ray strength decreased, and repeatability of the X-ray strength improved by directly cooling the electrode in a plasma X-ray source operated with a gas filled into a discharge tube. CONSTITUTION:A short circuit of a switch 6 causes an increase of a voltage between electrodes, first a discharge begins on an insulation material 3 surface, and plasma is generated. The plasma moves toward electrode open ends parallel to electrodes in a space put between both electrodes receiving a Lorentz's force, pinches by a magnetic field pressure when passed electrode ends, and radiates a soft X-ray with a spot of a high temperature plasma compressed in a high density formed on an tip axis of the inside electrode 1. The electrode is cooled directly by flowing a pure water in water-cooled pipes 8, 8', 9, and 9', a temperature on the electrode surface exceeding 200 deg.C can be reduced under 100 deg.C when not cooled in an operation. This results in a sharp decrease of an impure gas blown off in an operating gas from the electrode, an increase of a X-ray strength, and the sharp decrease of the decrease and variation of the X-ray strength.

Filed: 1990-10-25
Abstract: PURPOSE:To simply confirm an optimum exposure condition without using an optical microscope or the like by a method wherein contact-hole patterns or line-and-space patterns are arranged continuously and a semiconductor substrate is exposed to light by using a reticle in which their sizes have been changed stepwise. CONSTITUTION:A reticle 1 having a resolution pattern formed by sequentially and stepwise changing the size and the gap of contact-hole patterns 3 or line-and-space patterns is used; a resist film formed on a semiconductor substrate is exposed to light sequentially while the exposure time and a focal distance are being changed. The semiconductor substrate whose resist film has been developed is irradiated with light. An optimum exposure condition is judged by the difference in colors by the reflection of light. For example, a reticle 1 in which sizes of contact-hole patterns 3 have been changed in eight steps is used. Regions are shifted sequentially while the exposure time and a focal distance are being changed stepwise by using a reduction-type projection aligner; a resist film formed on a semiconductor substrate is exposed to light and developed. By checking the semiconductor substrate visually, the optimum exposure time and the optimum focal distance are judged.

Abstract: PURPOSE:To obtain a commutator segment with excellent material characteristics through means with high productivity by coating a fiber- reinforcing long fiber with matrix-forming copper and by pressurizing and sintering a composite material obtained through shortly cutting said workpiece. CONSTITUTION:A fiber is immersed in an electroless copper plating solution for 10-20 minutes so that a uniform copper layer of about 0.3-0.4mum thickness is formed on the surface of said fiber.

A wafer 5 is disposed and heated on a hot plate 6 within the chamber 4, and is irradiated with infrared rays 8 from infrared lamps 7. Heated resist on the wafer 5 is reacted with the gas 3. As the gas 3 is activated by the infrared rays 8, the temperature of the resist surface is increased abruptly, which accelerates decomposition of the hardened resist on the resist surface by thermal oxidation. In this manner, the resist hardened by ion implantation can be peeled off uniformly at a high peeling rate.
